PHOTO-INDUCED REACTION OF ALKYLATED 1,4-TOLUQUINONE CARRYING ESTER GROUP IN THE ALKYL SIDE CHAIN
摘要:
Irradiation of several 1,4-toluquinones 1a–d having functionalized side chain rapidly gave bicyclic phenolic compounds 2a–d in good yields via intramolecular hydrogen abstraction-proton transfer-cyclization. In the case of 1f, however, it was found that intramolecular rearrangement occurred concomitantly.
